Quels sont les risques du dopage ?

Quels sont les risques du dopage ?

Le dopage fait principalement peser des risques pour la santé. La consommation excessive de produits dopants entraîne ainsi de nombreux effets nocifs. Ces derniers peuvent survenir rapidement ou, à  l'inverse, apparaître longtemps après la prise du produit dopant. A chaque produit sont associés des effets nocifs.

Citons quelques exemples :

Les stimulants (caféine, amphétamines…)

Ils peuvent entraîner des troubles cardio-vasculaires (troubles du rythme cardiaque, infarctus du myocarde, accident vasculaire cérébral), des troubles neurologiques et neuromusculaires (troubles de la coordination, par exemple) et des troubles psychiques (agressivité ou dépression entre autres).

Les stéroà¯des anabolisants

Chez l'homme, ils provoquent des atteintes au niveau de la prostate et du foie, une augmentation de la taille des seins, des troubles de fonctionnement des testicules, une production réduite des spermatozoà¯des (avec un risque d'infertilité).

Les diurétiques

Ils peuvent provoquer une déshydratation aiguà«, des troubles cardio-vasculaires, une fatigue et un état de faiblesse généralisée, ainsi qu'un dysfonctionnement des reins.

Les hormones peptidiques

(EPO, hormone de croissance, DHEA) : les principaux effets indésirables de ces produits sont la survenue d'une insuffisance cardiaque sévère (pouvant entraîner un infarctus du myocarde, voire une mort subite), d'un diabète, de troubles sexuels et de cancers.

Tous les sportifs recourrant à  des produits dopants ne présentent pas systématiquement l'ensemble de ces troubles. Il existe en fait une variation importante d'une personne à  l'autre. Certains seront plus sensibles que d'autres aux effets indésirables d'une consommation de substances dopantes, sans que l'on puisse prédire à  l'avance le degré de sensibilité de chacun. Mais il n'existe pas d'individu qui soit totalement insensible aux effets néfastes des produits dopants.
